Description

Method for manufacturing a rectifier column device for a seawater desalination distiller. {Manufactured method fractionating column device of distiller for fresh water from sea water.}

The present invention relates to the production of a rectification column device of the seawater desalination still. The rectifier column device is composed of a collecting layer and a rash healing layer for collecting high temperature (boiling water). It was to develop a rectifier column device that condenses the steam of interest only in the cooler by suppressing the rising steam due to overheating in the evaporator.

Conventional seawater desalination apparatuses can be classified into low temperature evaporation, electrodialysis, reverse osmosis, and the like. These seawater desalination methods require high facility costs and high pressure systems. Small desalination facilities such as islands (books) usually require small-capacity facilities, so it is currently impossible to apply the technology of existing large-scale land systems. Although reverse osmosis is ideal, high pressure facilities of around 70 atm, such as primary and secondary processes, are required. Such seawater desalination is not suitable for producing beverages for a small island population.

There are many papers on desalination of seawater. It is said that it is suitable as a drink when 99.5% of salts contained in seawater are removed. However, in the present invention, can the salinity removal rate be increased to 99.99% with a small distillation apparatus? Was the inventor's goal.

As a result of measuring b.p of seawater, it was 100 degreeC, 102 degreeC, 103 degreeC, 104 degreeC, and 105 degreeC. Only steam at about 102 ° C can be bonneled into the condenser. A commercially available pure water distillation apparatus, 220V, 3KW, and 4 liters / hour capacity (1) was purchased. Between the evaporator and the cooler, a diameter of 160 mm and a pipe length of 150 mm were cut off, a column was installed, a lashing ring was filled, and seawater was distilled off. Only salty water was produced. Even if one small transformer was purchased and supplied again with 200V, 190V and 180V, only salty water was produced. 170V was supplied again and distilled, and it was not salty. However, yield was too low at 2.3 liters / hour. This is the cold distillation method. After repeated experiments, the rectifier column device was developed.

The rectifier column device is composed of a hot water collector layer and a lash-healing layer. The device thus manufactured is combined with a pure water production distillation unit and distilled sea water to produce only pure water. The pure water maker 220V, 3KW, 4 liters / hour distillation unit was combined with a distillation column unit and distilled sea water, 3.9 liters (3,900 g) of very pure water was produced. It was slightly lower than the net production amount of 4,000 g / hr of the pure water production apparatus purchased, but the yield was satisfactory as 97.5%.

Pure water distillation distilled sea water, only very salty water was produced. This is due to the salt (Nacl) content in seawater. Again, the salt was produced even after distillation by filling the lashing ring after installing the column in the lens after connecting the evaporator of the distillation unit with the cooler. The reason for this is that salts in seawater are the vapors of the salts in the evaporator that rise to the cooler and cool. Wouldn't it be possible to prevent this salt vapor from rising to the cooler? How can you prevent salt vapor from entering the cooler? This was a challenge.

To solve this problem, a pure distillation machine 220V, 3KW, and one production 4Kg / hr was purchased. The evaporator and the cooler were released, and the seawater was put in the evaporator to an appropriate level, and 220V and 3KW electricity were supplied. When the seawater boiled, the bubbles were severe and the foam overflowed by about 60% of the seawater's proper level. Then I thought that a column should be attached between the evaporator and the cooler. The flange between the evaporator and the cooler of the purchased distiller was 160 mm in diameter. It was 100 degreeC-105 degreeC when the boiling point (b.p) of seawater was measured. Therefore, in order to prevent it from rising to the rise cooler of steam of 102 ° C. or more, a length of 200 mm was cut in a pipe having a diameter of 158 mm, and a flange was formed at the top and bottom of the column. A space in which the liquid at 100 ° C. can stay was needed in this column. In other words, I imagined a collector that could hold liquid and made a collector. In addition, the Raschhiring was filled on the collector and hot steam was attached to the Raschhiring so that it fell into the collector. (20) Collector column distilled to make a salty water was not produced. However, microscopic pressure caused uneven production. It was driven again. This could be solved by adjusting the height of the collector in the manufactured column.

As a means of solving the problem, the desalination rate of the seawater was 99.99%. Due to global warming, drinking water shortage in the islands is coming. It is thought that the present invention is suitable for drinking water solution of a small island island. The rectifier column device of the present invention is applicable to seawater desalination of medium as well as medium and large. By combining this stop with various distillation units, it becomes a seawater desalination system. Example As shown in Table 1, the desalination rate is 99.99%, which is also suitable for drinking water. Therefore, the PCT international application is planned for distribution to all over the world.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Figure 2 is assembled to the general pure water production apparatus including the 20 rectification column apparatus. (10) The diameter of the column is to be calculated according to the capacity of the seawater evaporation system. Select the material by calculating the column diameter and length, make (27) and 28 flanges in the column, and make a (22) hydrothermal collector plate in the column. The hot water collecting plate is perforated (24) by FIG. (Figure 6 is based on 4 liters / hour capacity), the number of holes should be calculated according to the capacity. 5, the length of the return pipe of the collector is determined according to the seawater desalination capacity, the amount of reflux and the amount of reflux (24) to cut and weld the pipe. Make a rushing plate (23), and (23-a) a 3 mm hole anhydrous (or you can make a mesh) (20-h-1) (20-h-2) (20-h- 3) Calculate (20-h-4) distance (see Example) and assemble. Make lash healing ring, fill it with lash healing plate, and fill the flange with the evaporator and cooler at the bottom (28) and the top (27). Raschhiring specifications and quantities should depend on seawater evaporation. The rectifier column device is completed. The lack of content is described in detail in (Example).

Purifier distiller 220V, 3KW of Figure 1, 4,000g / hr purchased one was purchased. The diameter of the flange of the evaporator was 160 mm. 2 tons of stainless steel, 160 mm in diameter pipes were cut to 200 mm in length and made up and down (27) and (28) flanges. (22) The hot water collector plate was made of stainless steel 2t thick and 158mm in diameter. (24) Holes were drilled 40 with 10mm in diameter, and 10mm, 1t pipes were cut to 20mm in length and 40 were welded. (24) When the length of the fire pipe was 20mm, the amount of hot water collection was 260g, 390g at 30mm, and 520g at 40mm. Using a homogeneous material, the (23) Raschhiring plate was cut to a diameter of 158 mm in a circle (23-a), and 3 mm holes were drilled and assembled. (20-h-1) height 70mm, (20-h-2) height 20mm, (20-h-3) height 30mm, and (20-h-4) height 80mm. (22) The hydrothermal collector plate and (23) the rachhiring plate shall be assembled to be strictly level. (24) This is because hot water (100 ℃ hot water) is uniformly refluxed in the hot water reflux pipe and the hot steam of the salinity must be kept in contact with the hot water vapor of the evaporator to rise evenly. (28) Hurenji was assembled. (21) Rashiring makes and fills 160 pieces of stainless steel 0.5t, 22mm diameter and 22mm length. 27. Assembled Hurenji and condenser. 2, 10, 20, and 11 are assembled.

Sea water was distilled into seawater taken from the Yellow Sea. The coolant is supplied to (14) and drained from (15). Supply (17) seawater and (19) supply 220V, 3KW of electricity. Linked the lake to 16 and received the yield. After 20 minutes of electricity supply, production normalized and produced 3,9 liters (3,900 g) per hour. The yield was 97.5% compared to the 4 liter / hour capacity of the ready-made distillers. Analytical values of fresh water and sea water are shown in Table 1.
